Description

addPChargingFuncAddr

N/A

Enable flag to transparently pass P-Charging-Function-Address from ingress to egress message. This feature applies to all INVITE in-dialog requests and responses.

  • disable (default)
  • enable

audioCodecChangeThroughEmptyTcs

N/A

Enable flag to perform audio codec change (e.g. G.711 fax fallback) using empty Terminal Capability Set (TCS). When disabled, 

Unable to show "metadata-from": No such page "_space_variables"
performs audio codec change using request mode.

  • disable (default)
  • enable

clearmodeForDataCalls

N/A

Set flag to enable the clearmode function for data calls

  • disable (default) – If disabled for the SIP Egress call leg, legacy operation is signaled and payload type is assumed implicit (same on both sides). If disabled for the SIP Ingress call leg, legacy G.711 operation is accepted as well as Clearmode.
  • enable – If enabled for the SIP Egress call leg, Clearmode is sent using dynamic payload type. If enabled for SIP Ingress call leg, only Clearmode data calls are accepted.

disableConstrainedCapacities

N/A

Set this flag to present a full TCS to its peer during call setup or media modification. When disabled, 

Unable to show "metadata-from": No such page "_space_variables"
presents only the selected codec in the TCS, and follows up with a full TCS after media establishment.

  • disable (default)
  • enable

disableMediaLockDown

N/A

Enable this flag to allow 

Unable to show "metadata-from": No such page "_space_variables"
to disable media lock-down by not sending SIP Re-INVITE/UPDATE messages in the following scenarios:

  • Multiple codecs are sent in the offer and multiple codecs (or their subsets) are received in the answer, and the call becomes transcoded.
  • Multiple codecs are sent in the offer and a single codec is received in the response.
  • Multiple codecs are sent in the offer and a single codec with codec attributes is received in the response.

 If the result is a pass-through codec, and the most preferred codec in the answer (first codec in the list) is same as the selected codec, the

Unable to show "metadata-from": No such page "_space_variables"
disables media lock-down by not informing the egress peer using a re-INVITE.

  • disable (default)
  • enable

fromHeaderAnonymisation

N/A

Enable this flag to prevent the FROM header of INVITE message from being anonymized. The SBC always relays the FROM header of INVITE.

  • disable (default)
  • enable

includeG729WithG729aWhenOfferPspHasG729a

N/A

Use this flag to control whether the H.323 Service Group includes G.729 along with G.729A in the network offer when the 

Unable to show "metadata-from": No such page "_space_variables"
offer Packet Service Profile has G.729A.

  • disable (default)
  • enable

minimizeRelayingOfMediaChangesFromOtherCallLegAll

N/A

Enable flag to minimize relaying media changes to the other call leg by not sending re-INVITE messages from Server 1 to Server 2 in peer-to-peer pass-through without transcoding scenarios. This shields the call leg to Server 2 from the end-to-end propagation of SDP offers and answers. The 

Unable to show "metadata-from": No such page "_space_variables"
implements hold and resume operations for the call leg from Server 1 internally and responds with answers without signaling to the other call leg that media is being stopped or restarted.

  • disable (default)
  • enable
sendEmptyTcsN/A

Enable flag to send empty TCS to the peer to restart the peer’s forward channel in case there is an address update in the direct media case.

  • disable (default)
  • enable
sendRtcpPortInSdpN/A

Enable flag to send the RTCP port information in the SDP offer.

  • disable (default)
  • enable
terminalPortabilityInterworkingN/A

Enable flag to use Terminal Portability Interworking service between ISUP and SIP. The service enables a terminal to be moved from one socket to another or a call to be moved from one terminal to another within one call while the call is active.

  • disable (default)
  • enable
usePsxRouteforRegisteredInviteN/A

Enable flag to route INVITE from the core to the received PSX route for registered users, but not to the contact address of the RCB.

  • disable (default)
  • enable
